High-temperature alloys can be seen in aviation, power generation equipment and shipbuilding industries. This material can work for a long time under high temperature above 600 ℃ and certain stress. However, it is difficult to cut this material. Today Tingting learns with everyone through sharing with Li Shifu: What milling cutter is used to process high-temperature alloys with higher cost performance?

Iron-based high-temperature alloys: alloys based on iron or iron-nickel, the latter is also called iron-nickel-based alloys. Their oxidation resistance is not as good as that of nickel-based high-temperature alloys, and their high-temperature strength is far less than that of cobalt-based high-temperature alloys. However, due to the low nickel content, the price is cheaper, so it is widely used. Typical grades are GH2036, GH2135, etc. The machinability of iron-based superalloys is better than that of nickel-based or cobalt-based superalloys, similar to austenitic stainless steels.
Nickel-based high-temperature alloy: nickel-based alloy, for the current high-temperature oxidation resistance of the most stable class of materials, typical grades are GH4033GH4169, K403 and so on. The machinability of nickel-based superalloys is poor.
Cobalt-based high-temperature alloy: cobalt-based alloy, which is characterized by high temperature and high strength, can 100 more than the temperature, typical grades are K640 and so on. The machinability of cobalt-based superalloys is slightly better than that of nickel-based superalloys.
